Extendingdownward from the-bottom of "the casing" 20, and surrunding the pipel l9, is a tubular extension 25wli1chtermlnates in a cone 26 having a 'Eflange' 27 *Secured to the flange 27 byscrews 28 is a plate or, disk 29.

.1 3, and "directly under the recess-43, isan annular pipe 4A which isconnected with the recessifi3 bysh'ortrni'pples 45. The upper ends of these nipples extend to a point about 'inidway between the" bottoin and .top'; of the 'recess 43,which recess islocated directly below the o'uteredges of the disks 29 and 32.

y H waste pipe46 whichextendsto'any con- 0 is connected to the slde of the elbow 1 8 2and--* venient point outside of the casing 11. wLocated at a convenient place adj acent to the edges of thedisks 29 and 32 aresparking points 47 which are connected by wires &8

- Tl'ie device shown in the drawings is de- --si gned for-heating Y purposes, l as for house heating. It'may be used either :for heating ai'r or waten The device is placed inside of a suitable furnace, end combustion occurs aloove ring 41; and below the casing 20.

:held in place byscrews"33; 'Around the'boss 111 setting up the device the pipe 14 is connected to fan or other device'for forc The air flowing inward flowsaroun'd the teas- 24s tube 16, and entering below flows uniformly upward into the cage 4041. Here it first flows radially outward, then upward, and then inward and upward along the cone 26. By making the tube extend down to near the bottom of the chamber 10, there is no tendency for the incoming current of air thru tube 14 to cause the upward current to flow unevenly around the edges of the disks 29 and 32. i

' The pipe 24 is connected to a source of oil supply, but oil is not permitted to flow thru this pipe until the device has been started by other means.

The pipe 38 is connected to an ordinary gas main, and the flow of gas therethru is controlled by an ordinary valve or cock operated by hand. In starting, this pipe is opened and the fan started at about the same time. The gas flows thru the pipe 38, then upward thru tube 37, outward thru holes 09 into cone 26, downward thru holes 35 into recess 34, and then radially outward between disks 29 and 32 where it meets air flowing upward around the edges of said disks. At about the time the air and gas meet, or soon after it, the electrical devices connected to wires 48 are operated to produce a spark at 47 which will ignite the mixed air and gas. The resultant flame extends above the cone 26 and around the casing 20, the effect of which is to heat 'up said casing.

After the device has run for a few minutes in this way, the pipe 24 is opened by hand to admit oil, which oil flows upward thru pipe 19 and is discharged thru the branches 23 against the outer wall of the casing 20. As this casing is at this time surrounded by burning gas, it is heated and causes the gasification of the oil. This oil gas then flows downward thru openings 30, tube 25, cone 26, holes 35, recess 34 and space between disks 29 and 32, at the outer edges of which it meets the incoming air and is burned. As soon as this occurs, the gas coming thru pipe 38 is shut off and thereafter the device is maintained in operation by gas manufactured in casing 20 by the heat of the combustion maintained under and around it. To stop operation, it is merely necessary to shut off the supply of oil flowing thru pipe 24.

If a supply of permanent gas for starting purposes is not available, then pipe 38 is connected to a supply of some volatile liquid as alcohol. In starting under these conditions, the alcohol is permitted tofiow for a few minutes before the fan is started to force air thru pipe 14. In this case the alcohol flows over the course given for gas until it reaches the edges of disks 29 and 32. At this point it drips down into the recess 43, and forms a small annular pool not deeper than the height to which the nipples extend above the bottom of said recess. Under these conditions the alcohol will slowly vaporize. If now the current of air be caused to flow as before, it will pass over the surface of this pool and thru the liquid dripping downward to it. This will cause an increased vaporization of the alcohol, and a mixture of. the vapor and air. By simultaneous operation of the sparking device at this stage of the proceeding will ignite the mixture and cause a preliminary heating as described for gas.

In case oil should be flowing thru pipe 24 when the fire is not burning, then the oil would drip down. into the recess 43 and overflow thru nipples 45 and pipe 44 to the waste pipe 46.

It is to be observed that the air is conveyed in an annular current pastthe' edges of disks 29 and 32, and that the gas is projected radially into this annular current. The combustion is annular, and the gasifier 20 is located within this annular combustion. Taken together, the disks 29 and 32 may be considered as a disk having a disk-shaped passageway therein for gas.
